• Medium-speed trunk piston engines burning distillate fuels in marine main and auxiliary powerplant service. 

• Medium-speed trunk piston engines burning distillate fuels in stationary powerplant service. 

Maintains power output

The detergent/dispersant additive system provides control of high temperature deposits in areas such as the undercrown of the piston and the piston ring belt area, enabling piston rings to function efficiently. 

Prolongs oil life 

Base Number (BN) level and superior alkalinity retention characteristics maintain adequate BN to ensure corrosive acids formed by the combustion of fuel sulfur are effectively neutralized, thereby minimizing liner wear. 

Efficient purifying system performance 

Excellent water separation characteristics enable water to be centrifuged out with essentially no loss of additive. 

• Approved by major manufacturers for use in their medium-speed engines, including:  MAN Diesel & Turbo Wärtsilä
